A **null** **hypothesis** says there is no snificant difference between the results obtained and the results expected. For example let’s say an experiment was done with cats breading, one is true breading and has red eyes and brown coat and one is true breading and has green eyes and white coat.

*Hypothesis* Testing Examples Statistics That is, the test statistic *does* not fall in the "critical region." There is insufficient evidence, at the α = 0.05 level, to conclude that the *mean* Brinell hardness of all such ductile iron pieces is greater than 170. That is, the test statistic *does* not fall in the "critical region." There is insufficient evidence, at the α = 0.05 level, to conclude that the *mean* Brinell hardness of all such ductile iron pieces is greaterSince the biologist's test statistic, t* = -4.60, is less than -1.6939, the biologist rejects the *null* *hypothesis*.

*Hypothesis* Testing - Snificance levels and rejecting or **Hypothesis** **means** an educated guess about the outcome of an experiment. The **null** **hypothesis** is essentially the "devil's advocate" position. That is, it assumes that whatever you are trying to prove did not happen hint it usually states that something equals zero.

**Null** **hypothesis** - **Biology**-Online Dictionary For example, if you were to perform an experiment about how fast water boils depending on different temperatures your *hypothesis* may be "the hher the temperature used, the faster the water will boil" *Hypothesis* *means* an educated guess about the outcome of an experiment.
